ALBERT C. FRIESEKE, OF OWASSO, MICHIGAN.

Specification forming part of Letters Patent No. 118,229, dated August22, 1871.

To all lwhom fit may concern:

Be it known that I, ALBERT G. FRrEsEKE, of Owasso, in the county ofShiawassee and State of Michigan, have invented a new and usefulImprovement in Solde-rin g-Lamp and Blow-Pipe; and I do declare that thefollowing is a true and accurate description thereof, reference beinghad to the accompanying drawing and to the letters of reference markedthereon, and being a part of this speciiication, in which- Figure lshows my invention in perspective. Fig. 2 is a vertical section.

Li ke letters refer to like parts in each ii gure.

The nature of this invention relates to an improved construction oflamps and blow-pipes for the use of jewelers and other maiiufacturers.The invention consists in so arranging a lamp with a iiame derived fromalcohol that the iiame will be fed bythe volatile gas thrown ofil fromnaphtha by means of the blow-pipe, while at the same time the latter isemployed in giving direction and intensity to the tiame.

ln the accompanying drawing, A represents the lamp, divided into twocompartments, the one a being designed to be filled with alcohol andprovided with a wick-tube, b, of ordinary construction. The othercompartment c is designed to be partially filled with naphtha or itsequivalent. rlhis compartment is provided with a tube, B, which passesdownward through the top ofthe lamp and terminates near the bottom ot'the compartment. A smaller tube, d, leads from this compartment throughthe top. To the top of this tube the nozzle of the pipe G is secured insuch a manner that it may be removed at will or turned in any direction.A flexible pipe, D, is secured to the top of the tube B', and itsopposite end may terminate in a mouth-piece.

The compartment a being filled with alcohol, supplies the wick in thetube I). The compartment c being iilled about two-thirds full withi'iaphtha, and the nozzle of the pipe C being directed to the alcoholiciiame, a blast through the pipe D forces the air through the pipe B tothe bottom of the compartment c, whence the air rises, becomingimpregnated with the gas of the naphtha, and is forced through the tubeel and pipe C into the ilame, mingling said gas with the alcoholicflame, and greatly intensifying the heat. By mingling such gas with thealcoholic iame a great saving in the quantity of alcohol is had, and amore intense heat, at a small cost, than can usually be obtained fromalcohol, and by the use of my device the operator is not compelled touse one of his hands to guide his blowpipe and flame, but has both handsleft free to handle his work.

What I claim as my invention, and desire to secure by Letters Patent,is-` The soldering-lamp and blow-pipe described, wherein the lamp isdivided into two compartments, a and c, the former being provided withwick-tube b and the latter withtubes B and cl, in connection with thepipes C and D, the several parts being constructed, arranged,andoperated substantially as described and shown, for the purposes setforth.
